A stock market, stock exchange, or share market (sometimes referred to as the exchanges) is a place where the shares of a stock are bought and sold by an individual or a group of individuals. This market is usually located in a physical location, such as a stock exchange building or a stock market yard. In the United States, the busiest stock market is the New York Stock Exchange, also known as the NYSE, a few other large stock exchanges are in Chicago, San Francisco, and London. Many investors prefer to buy and sell their stock through a stock market because it allows them easier access to a wide variety of companies and trading opportunities. In addition, this type of investment has been proven to be very profitable.
One type of stock market is called the indices market. These are not actually exchanges where investors trade in individual stocks. Instead, they track the price movements of the indices (such as the Dow Jones Industrial Average or the FTSE 100) of particular companies. An index can be made up of hundreds of different types of financial products including treasury bills, mutual funds, stocks in companies that trade on international markets, and indexes of commodities. The major advantage to these types of indices is that they provide detailed information about the price movements of hundreds of different items at once.
An advantage of market indices is that they provide data at the same time several times throughout the day. This enables investors to monitor the changes in stock market prices over the course of several days. This can be particularly useful for stock market traders who want to get an image of how particular companies are doing. Investors who are unfamiliar with the concepts of market indices can use software called a trend line generator to help them make accurate predictions about where the trends might go next.
